So, probably you already know who I am.
I spoke with some people from VGPC who are also dumpers here (diego-rbb-93 and TonyLizard, cheers guys) and they convinced me that co-operation is in the best interests of everyone, regardless of past bad blood.
What I am proposing for starters is to contribute in your PSP stuff. This is a system I like and Redump dumping method is same as NoIntro. I have been contributing to them for several years already, so I guess submitting the same dumps to Redump is easy and beneficial to all.
I have a nice collection, about 200 UMDs right now. With TonyLizard we already identified several that are missing from your DB and the rest would probably be useful as verifies too.
If this goes well, we can always expand in the future to other systems, but let's try to start somewhere...
